about the module

mod_cband is an Apache 2 module provided to solve the problem of limiting users’ and virtualhosts’ bandwidth usage. The current versions can set virtualhosts’ and users’ bandwidth quotas, maximal download speed (like in mod_bandwidth), requests-per-second speed and the maximal number of simultanous IP connections (like in mod_limitipconn)

I advise using mod_cband by hosting companies, which would like to limit data transfer for their users, such as “10Gb of traffic per month”. There already exists the mod_curb module, which can limit data transfers, but it doesn’t work with virtualhosts and Apache 2, so I wrote my own module fully compatible with Apache 2 API and supporting per-user and per-virtualhost bandwidth limiting

The mod_cband Freshmeat record is systematicaly updated so if you are already a member of Freshmeat, you can subscribe to new releases and receive new version notifications from them.
